Application:
TDR test is the use of pulse reflection method, to transmit pulse signal for tested cable, when cable is
open circuit or short-circuit, reflected pulse is generated, the tester receives and deals with the reflected wave,
measurement results displayed on the screen. TDR can test cable open circuit and short circuit, help engineer
quickly find the cable's problem location. It is more convenient and efficient to repair the faulty cable.
Note: The TDR reflect signal could be affected by the cable quality cable's not well connected etc to
cause the different TDR measurement. The TDR measurement is for reference only.
